采用高效液相色谱-电感耦合等离子体质谱(HPLCICPMS)对采集于加拿大温哥华的褐藻Fucus gardneri中的砷形态进行了研究。采用氢化物发生-原子吸收光谱法(HG-AAS)测定总砷。与植物的其余部分相比，生长顶端中某些砷糖1的相对含量有所不同。夏季采集的岩藻样本总砷含量为9 ppm。大多数砷元素都是可提取的。冬季采集的岩藻样本含有相对较高的砷含量，为16-22 ppm，但只有少量的砷可提取。©1998 John Wiley&Sons，Ltd.
Arsenic speciation in a brown alga, Fucus gardneri, collected in Vancouver, B.C., Canada, was carried out by using high-performance liquid chromatography–inductively coupled plasma–mass spectrometry (HPLC–ICP–MS). Hydride generation–atomic absorption spectrometry (HG–AAS) was used for total arsenic determination. The relative amounts of some arsenosugars 1 in growing tips are found to be different in comparison with the remainder of the plant. Fucus samples collected in summer contain 9 ppm of total arsenic. Most of the arsenic species are extractable. Fucus samples collected in winter contain relatively higher amounts of arsenic, 16–22 ppm, but only low amounts of this are extractable. © 1998 John Wiley & Sons, Ltd.
